Lonove laptop won't come out it's built ino

Well a lot of batteries seem built in, but they are still removable. The shop/manufacturer would have to remove it to replace it just like you would.

If you are not sure you can do it without messing anything up, that is another story. In that case I would find a local tech/shop to do the work for you.

NOTE: If the device is still under warranty, do not do any work yourself or take it to anyone. In this case contact the manufacturer.
